This invention .relates to machines for printing floor coverings, such as linoleum, felt base goods, and the like, and relates more particularly to a color carriage for machines for this purpose.

In the manufacture of printed linoleum and allied floor coverings having multiple color designs printed thereon in oil paint, a specially constructed printing machine is employed having ahorizontal bed or platen on which the material to be printed'is supported, and above which are arranged a plurality of vertically reciprocable printing heads. These printing heads'are arranged along the platen, at regularly spaced intervals, and the goods is moved progressively beneath them in a step by step movement. Each of the printing heads carries a printing block or type face on the under side thereof, so that the pattern is printed by the lowering of the type face against the top surface of the goods on the platen. Each printing head has associated therewith a paint or color carriage. This carriage is supported in the machine frame in such manner that.

it can be rolled or passed under the print ing head when the same :is in an elevated position. The carriage is provided with a roll which contacts with the type to spread the paint on thetype. Thecarriages of the machine are all arranged to be reciprocated in unison, and are moved alternately in opposite directions under the printing face of the head, moving in one direction preceding one printing stroke and moving in the opposite direction precedingthe next printing stroke.

In machines of this character it has always been proposed that each color carriage apply one color only to its respective type, so that the design Which was printedwas strictly limited in the number of colors employed and in the arrangement-of such colors by the number of printing heads which could be accommodated in the given length of a printingmachine. r

According to the present invention it is proposed to divide the color carriageinto two or more compartments so that different colors can be put in different compartments of the same carriage. It is further proposed v to provide a construction wherein the paint irom one compartment is prevented from flowing over into the paint of the next adj acent compartment.

The invention may be readily understood by reference to the accompanying drawings,

which illustrate preferred embodiments of ofFigure 2;

. In the drawings, 2 designates the frame of a printing machine for printing floor coverings.- 3 is one of the'reciprocable posts provided at each side of the machine for supporting the printing head a. Secured to the under side of the printing head din the usual manner is a printing block 5 having projecting type faces. 6; v .The general construction of the machine is similar to that disclosed in United States Patent N.'1,263,900, dated April 23rd, 191 to Jones and Webster.

Mounted for movement beneath the printing head when the printing head is in an elevated position is paint carriage. This paint carriage comprises a trough whose length is substantially coextensive with the width of the printing machi The trough is mounted on rollers or gears 8, these gears riding on a rack 9. The carria re is connected with links 10 and 11 through which it is connected with the carriages of adjacent printing units, not shown. The links 10 and 11 are disposed the ends of the carriage so that they do not obstruct the vertical movement oi the printing head.

In its operation the carriage is normally positioned at one sioe or the other of the printing head. in. F' e l I have indicated in dotted lines the two dii'l erent positions of the carriage during the printing stroke of the printing head. When the orinting head is raised to the position shown in Figure l, the carriage moves from one of its positions to the other, and in doing moves beneath the printing head. In Figure l the full line position of the c: rriage indicates the paint-applying; position of the carriage.

Extending longitudinally oi the carriage in the trough thereof is a paint-applying roll 12 having trunnions 13 at the opposite ends thereof which are in hearings in the opposite ends oi the carriage. This roll is arranged to be rotated in the usual manner upon, reciprocation of the carriage, the earin through which this is eliected being now well understood in the art forming no part of the present inven ion. Consequently, such gearing has not been shown.

in the arrangement of the present invention as shown in Figures 2 to 5, the roll is of uniform diameter throughout its length, and there is set into the trough at a point intermeciate its ends a pa 'tition block 14. This block l i conforms to the shape of the trough, and has a. semi-circular recess 15 therein into which is set a semicircular band of packing or sealing material. 16. On the top of the block at each side or the roll is a recess 17. Suppor ed on the bl cl; each end thereof and at each side the roll are scraper or squeegee blades 18. These blades are located above the normal paint level of the trough and bear against the surface of the roll in such manner as to scrape clean that portion of the roll immediately adjacent the partition block. These scrapers or squee 'ee blades are relatively narrow as compared with the total length of the roll, and are used in addition to the usual doctor blades 19 ordinarily provided on color carriages of this nature; The doctor blades 19 are adjustable toward and away from the roll, and their function is to regulate and spread the film of paint carried by the roll up to the type surface of the printing block. In Figures 8 and 4 the doctor blades have been shown, but for the sake of clarity they have been omitted from Figures 2 and 5.

In the operation of the invention one color 01' paintcan be put into the compartment 20 at one side of the partition, and another color can be put in the compartment 21 at the other side of the partition. The number of partitions employed can be varied according to the design to'be printed. The partitions are held against movement during the operation of the printing machine by the holders for the doctor blade 19, as clearly shown in Figure 3. The packing 16 prevents the paint in one of the compartments from flowing around the roll into the other compartments. The scrapers l8 tend to clean the roll immediately adjacent the partition, but notwithstancn the provision of these scrapers, some paint will tend to iiow over the surface oi? the roll onto the partition. Such paint as works over onto the partition is collected in the recesses 17, so that it cannot iow from one compartment into the next, and the machine attendantcan remove the paint from the recesses 17 at such times as may be necessary by means of a bulb or other suitable means.

in Figures 6 to 10, inclusive, there i1- lustrated a slightly modified construction wherein th .11 partitions, instead of being formed separately from the trough of the carriagge, are formed an integral part there of. The construction of the roll is also modiied in this liorm of the invention. In these igures of the drawings, 22 is the trough can iage l'iavinp; bearin igs 23 at the ends thereof or supporting the roll 24. The roll 2-1, inead of being of uniform diameter throughu s entire length, has its diameter reduced i it those points in its length where the parvitions are provided. These reduced portions are designated 25. Formed in the trough 22 at those points where partitions are to be provided, are two spec ,l-apart partition members These pi ition members have semi-circular recesses 27 therein in which the roll received, and each partition has a groove 28 in the face of the recesses in The packing is which a packing 29 is set. for the purpose o'l preventing the colo 'ing material in the adjacent compartments from tlowin around the roll into the space between the partitions 26.

By reason of the reduced portions 25 in the roll, there is less tendency for the paint to spread over the roll than where the roll is of uniform diameter. Consequently, scraper or squeegee blades corresponding to the squeegee lDlflAlrBS 18 of the construction first de scribed not necessary, although these blades could be used if desired. Any paint that does tend to spread over the surface oi? the rolls onto the reduced portions thereoi. is collected in the space between the part? tions 26, and as the color material collects in these spaces it can be removed by an attendant. The usual doctor blades 19 are provided to extend across the entire length of the trough.

In Figure 6 there are shown three sets of partitions 26 dividing the trough into four separate compartments 30, 31, 32 and 33.

The advantages of the invention arise from the provision of a trough orcar'riage divided into compartments which can receive separate colors and which are so arranged that the paint from one compartment cannot work over into the paint in the next compartment. This division of the color trough allows for the arran ement of small type for small figures of different color upon a single head. This permits the printing of small portions of the design of the floor covering in ditierent colors by single head, whereas it has heretofore been necessary to provide a ditterent head for printing each of these small parts of the pattern.

A further advantage of the invention resides in the fact that. a variety of color can be obtained crosswise oi: the goods being printed thereb addineto the attractiveness of the pattern.
